INHALER.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed November 18, 1905. Serial No. 288,026.

To all whom it may concern:

Be it known that I, GEORGE F. HARTZ, a citizen of the United States ofAmerica, residing at Durant, in the county of Cedar and State of Iowa,have invented new and useful Improvements in Inhalers, of which thefollowing is a specification.

My invention relates to inhalers, and its primary object is to provide anovel and highly-useful device of this character wherein themedicament-containing tube is so arranged within a casing that the airis brought directly into the tube and discharged therefrom into thecasing, from whence it is conveyed to the user whereby to morethoroughly saturate the air, and thus provide a more effective device.

A further object of the invention is to provide an inhaler which issimple and durable of construction, one which may be easily and quicklyrefilled, and one which may be manufactured and sold at a comparativelylow cost.

l/Vith the above and other objects in view the invention consists in theconstruction, combination, and arrangement of parts hereinafter fullydescribed, claimed, and illustrated in the accompanying drawings, wherem Figure 1 is a central longitudinal sectional view of an inhalerconstructed in accordance with my invention, and Fig. 2 is a transversesectional view on the line 2 2 of Fig. 1 looking in the directionindicated by the arrow.

Referring to the drawings by referencenumerals, 1 designates a casing,which can be manufactured of hard rubber or any other suitable materialand which is provided with an entrance-opening 2 and a discharge-opening3. That end of the casing wherein is located the discharge-opening 3 isreduced to facilitate the application of the inhaler to the nostrils ormouth of a person.

A tube 4, which is designed to contain menthol or any other medicamentor combination of medicaments, is removably secured within the casing 1by means of an annular member 5. The member 5 is provided with anopening 6, adapted to receive one end of the tube 4 and has suchfrictional engagement with the casing 1 that all liability of itsbecoming displaced is obviated. The tube 4 has one of its ends closed bymeans of a screen 7, which may be constructed of any suitable materialand which is held in applied position by means of the member 5. The

tube 4 is provided with a plurality of openings 8, which increase innumbers gradually toward that end of the tube located adjacent thedischarge-opening 3.

The tube 4 may be supplied with menthol or any other medicament orcombination of medicaments, and the several parts of the inhaler may beassembled in the following manner.

The screen 7 is first stretched over one end of the tube 4 and is heldin applied position by the application of the member 5 to the tube. Thescreen provides a closure for one end of the tube 4, so as to preventthe displacement of the medicament, and after the same has been appliedthe tube is righted and provided with any suitable medicament. After thetube has been supplied the other end thereof may be closed by means of astopper composed of cork or any other suitable material. The tube is nowready for application to the casing 1, and it is supported centrallytherewithin by the member 5, which has such engagement with the casingthat all liability of the accidental displacement of the tube isavoided. The air enters the casing 1 through the opening 2 and passesdirectly into the tube 4 through its screen end. The air is thus broughtinto direct contact with the medicament, and it is passed from the tubethrough the opening 8 therein in a thoroughly-saturated condition. Thesaturated air is taken through the nostrils or mouth through theentrance-opening 3. The screen 7 not only provides means for retainingthe medicament within the tube 4, but also prevents dust and other fineparticles from entering the tube 4.

It is apparent from the above description, taken in connection with theaccompanying drawings, that I provide an inhaler wherein themedicament-tube is so secured within a casing that the air is broughtinto contact directly with the medicament, that I provide means whichnot only prevents the displacement of the medicaments within the tube,but also prevents the entrance of foreign matter into the tube, and thatI provide means which not only secures the tube within a casing, butwhich also retains the first-mentioned means in applied position.

Changes in the form, proportions, and minor details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having fully described and illustrated my invention, What I claim is 1.In an inhaler, a casing, a tube located Within the casing, a screenapplied over one 1 ing the screen in applied position, and the 15 tubeWithin the casing.

3. In an inhaler, a casing, a tube located Within the casing, a screenapplied over one end of the tube, and a member, said member beingadapted to retain the screen in applied 20 position and to secure thetube Within, and spaced from the inner Wall of, the casing.

In testimony whereof I a'l'lix my signature in presence of twoWitnesses.

GEORGE F. HARTZ.
